Parameters

• parameter INDEXNULLMARKER;
Override this parameter value to specify what value should be used as a null marker when a property of the type is used in a subscript of an index map. The default null marker used is -1E14, if none is specfied for the datatype. However %Library.PosixTime and %Library.BigInt datatypes could have values that collate before -1E14, and this means null values would not sort before all non-NULL values.

Methods

• abstract classmethod IsValid(%val As %CacheString) as %Status
Return $$$OK if the value is valid for the datatype, or an error code otherwise.
